How To Change MAC Address of Your Chromebook

Well, this is a pretty shameless copy-paste of François Beaufort’s post, but pretty useful, so I couldn’t stop sharing it. Now, there won’t be many who would want to do this, so if you are not the very curious type, you can probably skip this post.

How To Spoof Your Chromebook’s MAC Address

Your Chromebook needs to be on Developer mode for this to work.

– Open your Developer Shell
– Enter sudo ifconfig eth0 down to shutdown your internet connection
– Enter sudo ifconfig eth0 hw ether 00:11:22:33:44:55 to change your MAC Address
– Enter sudo ifconfig eth0 up to turn back on your internet connection.

If you are connected to the internet through WiFi, you just need to replace eth0with wlan0 in the instructions below.

Be careful, once you reboot your chrome device, the physical MAC address burnt in your network card will be restored.

  1. chronos@localhost / $ sudo ifconfig wlan0 down
    wlan0: ERROR while getting interface flags: No such device

    1. Use “sudo ifconfig” to see your devices.
      For me, it’s not “wlan0” it’s “mlan0”.

  2. it does not work

    chronos@localhost / $ sudo ifconfig wlan0 down
    wlan0: ERROR while getting interface flags: No such device

  3. Tried this but when I put in the first command it says eth0: error while getting interface flags: no subject device. Does the same thing if I try wlan0. Any advice?

    1. Steph the same exact thing happened to me I was in developer mode i did everything just like I was supposed to what did you do to fix it ?
